Microchip ATTINY861V-10SUR: An 8-Bit AVR Microcontroller Datasheet and Application Overview
The Microchip ATTINY861V-10SUR represents a powerful and versatile member of the renowned AVR 8-bit microcontroller family. Engineered for high performance in a compact package, this device is particularly suited for sophisticated applications requiring a rich set of peripherals within space and power constraints. This article provides an overview of its key features, datasheet essentials, and typical applications.
Housed in a 20-pin SOIC package, the ATTINY861V is built on Microchip's low-power picoPower technology, enabling it to operate at just 1.8V, making it ideal for battery-powered and energy-sensitive systems. The '-10' suffix denotes its capability to run at a maximum clock speed of 10 MHz. Its core architecture executes powerful instructions in a single clock cycle, achieving throughputs approaching 10 MIPS, ensuring efficient and responsive control.
The peripheral set of the ATTINY861V is remarkably comprehensive for its size. It features 8KB of in-system self-programmable Flash memory, 512B of SRAM, and 512B of EEPROM for non-volatile data storage. A standout feature is its two 8-bit timer/counters and one 16-bit timer/counter, all with complementary PWM channels, providing exceptional flexibility for motor control, power regulation, and signal generation. Furthermore, it includes an 11-channel, 10-bit Analog-to-Digital Converter (ADC), enabling precise measurement of multiple analog signals.
Communication is facilitated through a Universal Serial Interface (USI), which can be configured to handle SPI, I2C, and UART protocols, and a LIN capable USART. This allows for seamless connectivity with a vast array of sensors, displays, and other peripheral ICs. For enhanced system robustness, it incorporates a watchdog timer, brown-out detection, and an internal oscillator.
Typical applications leveraging the strengths of the ATTINY861V-10SUR include:
Sensor Hubs and Data Logging: Its multiple ADC channels and low-power sleep modes are perfect for aggregating data from various analog sensors.
LED Lighting Control: The high-resolution PWM outputs allow for sophisticated dimming and color mixing in lighting systems.
Motor Control: The fast PWM and timers are well-suited for controlling small DC and brushless DC (BLDC) motors.
Consumer Electronics: Used in handheld devices, remote controls, and accessories where small size and low power consumption are critical.
System Management: Functions as a intelligent power management controller or a secondary co-processor in larger systems.
ICGOOODFIND: The ATTINY861V-10SUR is a highly integrated and efficient 8-bit microcontroller that packs a significant number of advanced features into a small form factor. Its combination of ample memory, versatile timers, a multi-channel ADC, and ultra-low-voltage operation makes it an outstanding choice for designers tackling complex embedded challenges in power- and space-constrained environments.
